AD9851 180 MHz完整DDS频率合成器

AD9851是一款高度集成的器件,采用先进的DDS技术,内置一个高速、高性能数模转换器和比较器,共同构成数字可编程频率合成器和时钟发生器。以精密时钟源作为基准时,AD9851能产生一个频率稳定、相位可编程的数字化模拟输出正弦波。该正弦波可以直接用作频率源,或在内部转换为适合捷变时钟发生器应用的方波。

AD9851的创新型高速DDS内核提供一个32位频率调谐字;对于180 MHz基准时钟,输出调谐分辨率可以达到0.040 Hz。AD9851内置独特的X6基准时钟乘法器电路,无需高速参考振荡器。该6X PLL乘法器对无杂散动态范围(SFDR)和相位噪声特性的影响极小。该器件还提供5位数字控制相位调制,使其输出能够以180°、90°、45°、22.5°、11.25°及其任意组合的增量发生相移。
